A multimedia platform records a performance on a keyboard synchronously with a picture by periodically regulating an internal clock, which is indicative of the lapse of time, with time codes inserted into the set of video data codes representative of the picture, and reproduces the performance through an automatic player piano also synchronously with the picture by periodically regulating the internal clock with the time codes, whereby the user enjoys himself or herself in the performance as if he or she feels himself or herself performing in a convert hall.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A multimedia platform for reproducing at least first music sounds synchronously with a picture, comprising: a first data source outputting a first sort of data containing pieces of first music data information representative of said first music sounds and pieces of first time data information representative of a first time defined from a first viewpoint; a second data source outputting a second sort of data containing pieces of video data information representative of visual images of said picture and pieces of second time data information representative of a second time defined from a second viewpoint different from said first viewpoint; an image generator connected to said second data source so as to produce said picture from said pieces of video data information; a sound generator connected for generating said first music sounds from said pieces of first music data information; and a timing controller incrementing a third time defined from said second viewpoint and represented by pieces of third time data information, connected to said second data source so as to compare said pieces of third time data information with said pieces of second time data information to see whether or not said third time is consistent with said second time, connected to said first data source so as to modify said pieces of said first time data information with the negative answer for eliminating a time difference from between said second time and said third time, converting said pieces of first time data information to pieces of fourth time data information representative of a fourth time defined from said second viewpoint, comparing said pieces of fourth time data information with said pieces of third time data information to see whether or not said third time catches up said fourth time, and further connected to said sound generator so as to transfer said pieces of first music data information to said sound generator when said third time catches up said fourth time, wherein said pieces of first time data information define time intervals to be inserted among said pieces of first music data information, and said pieces of second time data information define a lapse of time from an initiation of reading out said pieces of video data information.
2. The multimedia platform as set forth in claim 1 , in which said pieces of third time data information define a lapse of time from an initiation of reading out said pieces of first music data information, and said pieces of fourth time data information represents an accumulated total of said time intervals.
3. The multimedia platform as set forth in claim 1 , in which said first data source includes a floppy disc player, said second data source includes a video camera, and said sound generator includes an automatic player piano.
